5. 4. Improving the guidance, navigation and control design of the KNATTE platform

   University essay from Luleå tekniska universitet/Institutionen för system- och rymdteknik

   Author : Lars Lundström; [2023]
   Keywords : Multisensor Data Fusion; Nonlinear Kalman Filter; Neural Network;

   Abstract : For complex satellite missions that rely on agile and high-precision manoeuvres, the low-friction aspect of the space environment is a critical component in understanding the attitude control dynamics of the spacecraft. The Kinesthetic Node and Autonomous Table-Top Emulator (KNATTE) is a three-degree-of-freedom frictionless vehicle that serves as the foundation of a multipurpose platform for real-time spacecraft hardware-in-the-loop experiments, and allows emulation of these conditions in two dimensions with the purpose of validating various guidance, navigation, and control algorithms.

6. 5. The influence of soil modeling on the prediction of vehicle dynamics and mobility – A comparison between the Finite Element Method and a Semi[1]Empirical Model

   University essay from Uppsala universitet/Institutionen för informationsteknologi

   Author : Jimmy Kjellqvist; [2023]
   Keywords : ;

   Abstract : This master's thesis investigated the influence of soil modeling on vehicle dynamics and mobility predictions with a focus on two different soil models implemented in Project Chrono: the Bekker-Wong model, and a Finite Element (FE) model. The primary objective is to provide insights for decision-making regarding the most suitable soil model under specific circumstances. READ MORE
